If you want to experiment with auctions, you can use acceleration mode and start your auction name with “TESTING”.

Acceleration mode was developed to enable the procedure testing in the sandbox and to reduce time frames of this procedure.

To enable acceleration mode you will need to:

add additional parameter mode with a value test;

set quick,accelerator=1440 as text value for procurementMethodDetails. This parameter will accelerate auction periods. The number 1440 shows that restrictions and time frames will be reduced in 1440 times.

set quick as a value for submissionMethodDetails. This parameter works only with mode="test" and will speed up auction start date.
